Roamic does not provide an unlimited data eSIM for Madagascar. All Roamic plans listed for the country have a hard data cap, such as 50GB, 20GB, 10GB, or 5GB, each bundled with a fixed validity period of 30 days or 21 days. Because the caps are fixed, the amount of data that can be used is limited to the specified allowance.
If a traveler needs a larger data allowance, Roamic offers fixed data plans with substantial caps. For example, the Madagascar eSIM 50GB plan gives 50GB of high‑speed data for 30 days at a price of $190.54 USD, while the 20GB plan provides 20GB for the same period for $87.42 USD. These fixed plans can be more cost effective for most users, unless a very heavy data consumer requires a truly unlimited option, which is not available from Roamic.
